Application fled November 1a, 192:. Serial in. 674,236. I

To all whom it may concern:

Be it known that I, Josnrn Sonrmmma, a citizen of the -United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented a new and useful Distillation A paratus, of which the followin is a speci cation. g

- The present invention relates to improvements in the construction of distilling columns and more particularly to the construction of the parts making up the distilling or stripping section thereof. The construction of the present invention is more particularly suitable for use in distilling columns of the type described in my copending application, Serial Number 433,376, filed December 27, 1920," and in my co-pending application, Serial Number 674,285, filed of even date herewith. The invention will be more fully understood from the following description, illustrated by the accompanying drawings in which,

Figure 1 is a vertical sectional view through a portion of a column embodying the present invention;

Figure 2 is a transverse sectional view on the line 2-2 of Fig. 1.

In Figure 1 of the drawings there is illustrated a portion of a distilling or stripping section of a unitary column construction, this section being made up of superimposed units 14, of which any desired number may be employed. Each of these units is provided at its upper end with a flange 22 of generally triangular form and with a shoulder 23 into which the wall of the next unit above is fitted. This construction of 'oint between the sections is more fully set orth in my prior Patent Number 1,366,955.

Within each unit the baflle ring 25 is secured to the wall and extends inwardly, leavin a central opening 25" for the passage 0% vapor and liquid. From the inner rim of the bafile ring 25 a cylindrical skirt 26 depends, and isprovided with ripheral openings with inwardly directe vanes 28 which function in a manner similar to the vanes of a turbine rotor, imparting to the vapor passing through them a positive rotary or whirling movement.

Above each of the baflle rings 25 is provided a deflector plate 30, which is arranged centrally within the column, its outer rim being s aoe'd from the wall "to pro.

vide a ree assage for vapors. From the outer rim 0 the deflector late 30 a cylin= drical skirt 31 depends, t"s skirt "resting I upon the bafil'e ring 25 and serving as a supp'ortfor the deflector late 30. 'The skirt.

31 is preferably provi edat its lower end with short projecting lugs, which leave a :pace between it and the baflle ring 25' for e passage of liquid. The depending skirt 31 is provided with peripheral openings 32,

and with outwardly promoting vanes'33 at each of these openings, these vanes functioning in a manner similar to those pro vided in the depending skirt 26, as [hereinbefore described.

In the preferred construction shown in the drawings, the bafile rings 25 are given aslight downward pitch and the deflector plates 30. are constructed as relatively flat cones with a slight pitch. a

In Figure 1 of the drawings, the distribution of in-fed liquid is also shown. ,A section or unit 35 is provided at a suitable point in the column, into which the pipe 16 carrying the material to be distilled is brought. This pipe terminates in a downwardl depending portion 16, which opens direct y above the center of the deflector plate 30 of the next lower unit, the in-fed mlaterial being properly distributed by this p ate.

In operation, the vapors from below rise around the cylindrical skirt 26 depending from the bafile ring 25. They are forced by the baflie ring to pass through the openings 27 in the skirt 26 and in doing so, are given a positive rotary or whirling motion by the vanes 28. As they continue their rising movement, they are forced by the deflector sive and intimate contact between the liquids and the vapors. Similarly, the baffle ring 25 causes the liquid to be guided to the interior of the depending cylindrical skirt 26, where a like subdivision and contact between rising vapors and descending reflux is brou ht about by the action of the vanes 28. n this manner, an extremely efi'ective heat interchange results between the reflux and'the vapors.

I claim: I

1. In a column still construction, a unit havin a baflle ring extending from its wall inwar l to an open central space, a cylindrical shirt depending from the inner rim of said ring, peripheral openings in said skirt and vanes at each of said openings for imparting rotary movement to vapors passing therethrough.

2. In a column still construction, a unit having a central deflector plate providing an open space between its outer rim and the wall of the unit, a cylindrical skirt depending from the outer rim of said deflector plate, said cylindrical skirt being provided with peripheral openings and vanes at each of said openings for imparting rotary movement to vapors passing therethrough.

3. In a column construction, a unit having a bafiie ring extending from its wall to an inner central opening, and means for guiding descending liquids directly downward from said opening and imparting rotary movement thereto within the opening,

4.,In a column construction, a unit having a bafiie ring extending from its wall to an inner central opening, a central deflector plate above said baflie ring, said plate leav- V mg an open space between its outer rim and thewall of the unit, means for guiding des'cending liquid from the rim of the deflector plate downward and bringing vapor, into contact therewith with a positive rotar movement and means for guidin descen ing liquid downwardly from t e central opening in the baflie ring and for bringing vapor into contact therewith with a positive rotary movement.

5. In a column construction, a condenser unit having a downwardly pitched baflle ring extending fromits wall inwardly, a cylindrical skirt depending from the inner rim of the bafiie ring, said depending skirt being provided with peripheral openings and with internally directed vanes at sald opening, a central deflector plate above the bafiie ring, a cylindrical skirt depending from its outer rim, said skirt resting upon the bafiie ring and" thereby supporting the deflector plate, the skirt being provided with peripheral openings and with outwardly directed vanes at said openings.
